The invention relates to an instrument cross beam and a manufacturing method thereof, the instrument cross beam comprises a tubular beam and a plurality of mounting brackets, and the plurality of mounting brackets are sequentially arranged on the tubular beam along the length direction of the tubular beam and are integrally formed and connected with the tubular beam. The manufacturing method of the instrument cross beam comprises the following steps: S1, putting a round tube blank into a mold, heating to a required temperature, and closing the mold; and S2, a high-pressure liquid medium is injected into the round pipe blank, high-pressure forming is conducted in the round pipe blank, the pipe beam is obtained, meanwhile, a liquid raw material is injected into the mold, and the mounting support is obtained through die-casting forming. And S3, cooling and demolding. Compared with the prior art, the instrument cross beam provided by the invention adopts an internal high pressure and die-casting composite molding manufacturing method, the process is simple, the structure is firm, the size control precision is high, the deformation or distortion of parts can be inhibited, and the weight is reduced by about 30% compared with a steel instrument cross beam.

    本发明涉及一种仪表横梁及其制造方法,该仪表横梁包括:管梁和若干安装支架,多个所述安装支架沿所述管梁的长度方向依次设置于所述管梁上并与所述管梁一体成型连接。该仪表横梁的制造方法包括如下步骤:S1、将圆管胚放入模具中,加热至所需温度并合模;S2、向所述圆管胚内注入高压液体介质,使所述圆管胚内高压成型得到所述管梁,同时向所述模具内注入液态原材料,压铸成型得到所述安装支架。S3、冷却并脱模。与现有技术相比,本发明提供的仪表横梁采用内高压及压铸复合成型的制造方法,工艺简单,结构牢固,尺寸控制精度高,能够抑制零件变形或者扭曲,并且相较于钢制仪表横梁减重达30%左右。
